Please help me I’m stuck 😭

I’ll just start out by saying I’m 18 my fiancé is 20, we’ve been together for 2 1/2 years and there’s a huge chance of pregnancy right now. He’s working full time so I don’t have to but half of our family is super supportive and the other half... not too much. He’s always talking about wanting a mini us cause we both love children but after he spoke to my father last night he goes “I really hope your period comes.....” in a worried voice and I’m ripped in so many different emotions. I don’t know what to do.... we’d keep the baby if I am but I feel like we’d get so much hate.... 🙁 what should we do? Please help I need advice I don’t have very many people I can trust that’s why I’m posting ..
